Direct Factory Custom NdFeB Magnets
Neodymium Iron Boron (NdFeB) is a rare-earth permanent magnet made of neodymium, iron, and boron. Known as the “King of Magnets,” it is currently the strongest permanent magnet available.
-
Can lift up to 640× its own weight
-
Magnetic energy per volume 18× ordinary ferrite
-
Prone to oxidation, requires surface coating
-
Coating options: nickel, zinc, epoxy, or no-coating technology
Overview
Neodymium Iron Boron (NdFeB) Magnets
Magnetization Direction of NdFeB Magnets
- Material Composition: Made of neodymium, iron, and boron, with chemical formula Nd₂Fe₁₄B. Certain other metals are added in precise proportions and processed through multiple metallurgical steps.
- NdFeB Types: Divided into sintered NdFeB and bonded NdFeB. The so-called “King of Permanent Magnets” is sintered NdFeB because its magnetic performance is far superior to bonded NdFeB.
- Manufacturing Process: Ingredient preparation → smelting → powdering → pressing → sintering (for sintered NdFeB) → machining → magnetization. Machining may include grinding, slicing, wire cutting, drilling, sleeving, electroplating, etc.
- Surface Treatment: Common coatings include zinc plating (e.g., colored zinc, blue-white zinc), nickel plating, Ni-Cu-Ni plating, and paint. Less common methods include epoxy coating, electrophoresis, phosphating, gold plating, silver plating, chrome plating, etc.
- Applications: Motors, VCM, speakers, MRI, magnetic separation equipment, and more.
Applications of NdFeB Magnets
NdFeB magnets are widely used across various industries due to their strong magnetic performance and reliability. Common applications include:
- Motors: High-efficiency electric motors for automotive, industrial, and consumer devices.
- Voice Coil Motors (VCM): Precision actuators in cameras, hard drives, and optical equipment.
- Electronics & Audio Devices: Speakers, headphones, microphones, and magnetic sensors.
- Medical Equipment: MRI machines, medical imaging devices, and laboratory instruments.
- Magnetic Separation Equipment: Industrial magnetic separators for recycling, mining, and material processing.
- Other Uses: Renewable energy generators, robotics, magnetic locks, and other precision devices.
